I think people aren't grasping the full scope of 72 Slaughter, honestly.

The Alpha (a) bots on the 3 exterior Bases are worth 15 Points Each Plus a Team Wide damage buff. Technically, you could abandon mid entirely after the first add (y) and rack up 45 kills worth of points by taking all 3 of the side objectives. iirc the center one is worth about 30 plus a hp/mp buff, so you actually make out better overall prioritizing the side objectives and attempting to take 2.

The problem is co-coordinating your team to do this and the center winds up being a clustered mess of feeding kills to CC/Cometeror combos.

It's actually that lack of cohesive teamwork that makes 24 man slaughter feel so much better as it's there is a lot easier time working with 7 others, than 23 others to work together.

Slaughter is objective based. It's just that players do not value the objectives as much as they should. It's a new mode though so it might catch after people become more accustomed to it.
